Description

DETAILED DESCRIPTION OF THE INVENTION The present invention moves inside an air conditioning duct, etc. by spraying a cleaning liquid on the inner surface of the tact, or by brushing the separated f'3 waste material without spraying. The present invention relates to a cleaning method and an apparatus for cleaning a dirt bag 1 in which suction is sucked out from a vacuum suction port adjacent to a brush by a vacuum cleaner cooperating with a trolley.

Conventionally, this type of duct cleaning method and its equipment include the Dug 1
- Holes (point 1) were drilled on the bottom surface every 3 to 5 meters, a brush was inserted through the hole, and the brush was rotated from outside to clean the inside of the tact, and compressed air was supplied. Whip cleaning is also used to clean the inner surface of the duct by inserting a tube through the shaped hole and making a whipping motion to clean the inner surface of the duct, separating the dirt adhering to the inner surface of the duct, sending the scattered dust to the downstream area, and cleaning the duct. ACVA that vacuums at the terminal
Fix a suction botukunu made by Campus to the underside of the system (Nippon Winton Co., Ltd.) or the inspection port of the duct.
Insert the high-pressure air hose with the end connected to the air congressor through the high-pressure air hose insertion hole made by Canvas attached to the bottom of the suction box, and insert the air nozzle at the tip of the high air hose into the high-pressure gamma-hose insertion hole. Stirring the dirt inside the tact chamber by inserting your hand from the outside, storing the separated contaminants in the satanyon box, and suctioning them with a wet dust collector through the suction box (Kanhas duct) attached to the bottom of the suction box, etc. However, in both cases, contaminants fall onto the indoor floor through holes or the gap between the inspection port and the satanyeon hotspot, so it is necessary to cure the indoor area over a wide area, and the work is done on Saturdays and Sundays.
Cleaning is limited to holidays such as Sundays and holidays, and there are few openings and inspection ports, so sufficient cleaning cannot be done, and mechanical equipment or jigs have not been developed. Manual work is inefficient, and in addition, the dust on the inside of the duct is vacuum-collected by brushing, etc., but the dust is not completely collected due to the speed of the dust-collecting air inside the tactile duct, and there is a large amount of dust. There are various drawbacks, such as difficulty in /Δ sweeping in the case of sticky metals with high humidity.

Moreover, the conventional tact cleaning method and device? This method has the disadvantage that it is impossible to clean damaged items such as oil and cool particles stuck to the return tactile chambers, and it is also impossible to clean dust in the return tactile chambers of department stores, restrooms, etc.

However, in the present invention, a trolley that can travel within the duct is provided, and the trolley is remotely controlled to travel within the duct.
A rotating brush installed at the front of the trolley brushes the inner surface of the duct with or without spraying cleaning liquid.
The dirt separated from the inner surface of the duct is scraped to the rear of the plan, and the vacuum hose is sucked out with a vacuum cleaner at /i L from the vacuum suction port that opens close to the rear of the brush and operates in conjunction with the trolley. ACVA of
There is no need to drill many holes penetrating the ceiling surface every 3 to 5 meters below the duct of Sinutem's ZD, and it is only necessary to drill one hole on the side of the duct where the trolley can be put in and taken out. The dust collection wind speed is strong, and the dirt separated from the inside of the duct is completely collected, and there is little dust floating up, and the only place to cure is the hole where the trolley is taken in and out.
It is possible to work on days other than holidays such as Saturdays, Sundays, and holidays, and since the trolley travels inside the duct, thorough cleaning can be performed, even in return ducts of department stores and toilets, etc.
A limit switch is installed on the truck frame, and by disconnecting the clutches installed on the front and rear sprocket shafts, one of the caterpillars on both sides can be rotated or stopped in the same manner as the other, allowing the truck to travel. In addition, in the case of fixed dust containing oil, tar, etc. in kitchens, etc., spray cleaning liquid such as detergent and foam by brushing and suck out the separated contaminants from the inside of the duct together with the foam. It can be handled even if

Moreover, by connecting the trolley and the control panel with a control cap tire, the trolley can be controlled remotely by operating the control panel, making it possible to mechanize the cleaning device, resulting in labor savings and increased work efficiency. It is possible. In addition, a similar trolley containing a video camera for inspection instead of a rotating brush is placed inside the duct and monitored from outside on a monitor, allowing the user to check the condition inside the duct before cleaning and after cleaning is completed. The situation can be checked. Reference will now be made in detail to the accompanying drawings, which illustrate one example of carrying out the invention.
